---+++ LHCb Physics Software sources

The LHCb projects are hosted in the gitlab instance, hosted at CERN, in the "lhcb" group:

https://gitlab.cern.ch/lhcb

---+++ Nightly builds & Unit testing

The LHCb Core Software runs a continuous ntegration system described in:

https://twiki.cern.ch/twiki/bin/view/LHCb/LHCbNightlies

The status of the builds can be found at:

https://lhcb-nightlies.cern.ch/nightly/

The configuration for the system can be found in git at:

https://gitlab.cern.ch/lhcb-core/LHCbNightlyConf

(Some description of the Nightly build slots is [[LHCbDevOptsSlots][here]])

The nightly builds are driven by the following instance of Jenkins:

https://jenkins-lhcb-nightlies.web.cern.ch/

---+++ Installation of the nightly builds

After build the nightly slots are installed on the CVMFS volume: =/cvmfs/lhcbdev.cern.ch=.

XXX Link CVMFS Dev release documentation

Messaging between Jenkins and the CVMFS LHCb Stratum-0 node (cvmfs-lhcbdev) is hosted via an instance of the =rabbitmq= messaging engine described below.
